Disagree. Our empire enables us to have cheap goods and higher quality of life. War is generally bad for both, and since the second world war, when we really starting spending money on the military, other than terrorists, we have not been attacked by a nation state. The money spent on the military is worth every penny. The world has pretty much been unipolar since 1990, and is now becoming multipolar with the rise of China and India. A multipolar world will have much more conflict than unipolar or bipolar. Our strong military has maintained general stability in the world since the 40s and we need to keep it growing so the world does not become multipolar again, if we are dominant, other countries will join us and not fight us.
